Commodity characteristics: Man-made fibre filter material with gradually widened relative density, high cost-performance ratio, low initial friction resistance, high dust capacity, ductility, safe production and convenient use. This product series is mainly used for the pre-consideration of purification equipment. It is a common filter system in air filtration, which is widely used to filter large amount. Particle dust and suspended solids (> 5 um) in the gas are dominant. It is suitable for pre-filtration of air filtration system where filters need to be cleaned frequently. The main components are: PET (polyester fiber) and P P (polypropylene fiber). Hot air method and needling method are commonly used in the production process.
Filtration efficiency: For 5 micron particles, the filtration efficiency is 40%, 65%, 80%, 90%, and the European specifications G1, G2, G3, G4, EUROVENT4/5: EU1, EU2, EU3, EUROVENT4/5.
Type: filter pad or filter roll, can be cut according to the size of the air outlet, installed directly to the air outlet, the windward surface is usually white, can be added color, green, blue, yellow, etc. After waterproof treatment, it has the cleaning function. It can be used in automatic coiling filter unit after single-sided netting, coiling core and paper tube.
Initial effect filter
Usage Conditions: Temperature: - 10 ~ 100 C, humidity: < 80%, air filtration with slight acid and alkali.
The service life of the filter cotton can be normally used for 1 to 2 months under the rated air flow condition, i.e. the filter cotton needs to be replaced; or when the resistance of the filter cotton reaches more than 200 Pa, the filter cotton must be replaced; if the filter cotton is washable, the filter material replaced can be washed and compressed with clean water or a solution containing neutral detergent. Air-dried or cool-dried, and then replaced; more permissible cleaning twice, that is, new filter cotton must be replaced, and each cleaning, filtration efficiency will be reduced by 15%. If the dust concentration in the use environment is high, the service life will be reduced.
Scope of application: Used in various industrial uses: such as spraying industry, electroplating industry, surface treatment, exhaust gas treatment, building ventilation, pollution prevention, public construction, air conditioning industry, household appliances industry, automobile industry, motorcycle manufacturing, electronics industry, watch industry, pharmaceutical factory, food industry, packaging materials, furniture industry, decoration. Engineering and other ventilation air conditioning systems in various areas of air purification.
Commonly used specifications are 1m or 2m wide. Other specifications can be customized according to requirements. The length is unlimited. Generally, they are 20m or 40m, and the thickness is 0.5mm-50mm.
